EEG in game user analysis: A framework for expertise classification during gameplay

Abstract

Video games have become a ubiquitous part of demographically diverse cultures. Numerous studies have focused on analyzing the cognitive aspects involved in game playing that could help provide an optimal gaming experience level by improving video game design. To this end, we present a framework for classifying the game players expertise level using wearable electroencephalography (EEG) headset. We hypothesize that expert/novice players brain activity is different, which can be classified using the frequency domain features extracted from EEG signals of the game player. A systematic channel reduction approach is presented using a correlation-based attribute evaluation method. This approach identifies two significant EEG channels, i.e., AF3 and P7, from the Emotiv EPOC headsets fourteen channels. The features extracted from these EEG channels contribute the most to the video game players expertise level classification. This finding is validated by performing statistical analysis (t-test) over the extracted features. Moreover, among multiple classifiers used, K-nearest neighbor is the best classifier in classifying the game players expertise level with up to 98.04% classification accuracy.
